creating and deleting entries works great, but updating does not work -
for some reasoen after clicking the update button, i go back to the index page but no changes are saved.
I'v put a break point right before the SaveChanges(), i see that the form colection shows the new data, but it's not geting into the db?

I have a strange issue with the FormView. After working through some issues getting the update to work (as this is my first experience with FormViews) I now have a new issue. After I perform an update, and the FormView updates and returns to read mode, if I hit F5 (refresh) the FormView performs another update to the datasource, despite the fact it is read-only mode and none of the fields on the screen are editable.
I would think that a refresh in read mode for the FormView after an edit would simply refresh the data from the database, not perform another update. Again, the FormView is in Read Only Mode, but a refresh is creating another Update event (which I can debug and see if I break in the ItemUpdating event). This only happens after I perform an edit, not when the page initially loads.
I have a detailsview control linked to a SQL DB. I have created a template field with various controls within. When I click on edit and change the values and press update. The detailsview control changes back to read only and displays the original values. I have attached the code for the control and datasource below.

where I have gone wrong? changing from VS2003 DataGrid to VS2010 GridView; still on SQL Server 2000 so the wizards for autogenerating the code are not compatible.

Is there a way to update a value in a gridview, by pressing a button that shows within the cell? For example, i have a really simple gridview showing supply levels, I havr the following SQL table:
ID = Int
PartNumber = varchar
Quantity = Int
I would like to be able to press a "Plus" or "Minus" button on the gridview next to the Quantity (in stock) value which updates the database and re binds the data to the gridview, but without going into edit mode.
I have a gridview and detailview in an updatepanel. My detailview is setup to display the details of a record that is selected in the gridview. When I edit the values in the detailview and click update it does not update the gridview. If I check my database the values have been changed it just haven't been updated in my gridview. Below is my code for the two objects and their datasources.
<asp:GridView ID="GridView1" runat="server" AllowPaging="True"
AutoGenerateColumns="False" DataSourceID="RCR_DSM" AllowSorting="True"
DataKeyNames="PartNumber" AutoGenerateSelectButton="True">

I'm using a formatting expression with a template field. When the details view goes into edit mode the formatting is applied. It looks great because it applies the currency formatting. It shows up as "$60,000.00" instead of "60,000.0000". But then when I do the update it gets rejected because of the $. Is there a way to keep the formatting for the user to see in edit mode but remove the $ when doing the update so I don't get the error?
The error: Exception Details: System.FormatException: Input string was not in a correct format.

I'm new to asp.net 3.5 and I have been working through the tutorials using a real access database to learn how to use the new controls. I have an extremely simplistic page setup with a master-details view, the master using the gridview, and the detail using the detailsview controls. Everything seemingly functions correctly, except when I try to update the data in the details view. I make changes to the record, click update and the page posts back but nothing is updated in the database. No errors are given either.
View 10 RepliesI have used this before with no issues. Now I get to the page with the detailsview using parms I pass with the key to the row. When the page opens the row I want to update is displayed.
I am having 2 issues. One when I change any of the fields and hit Update (the Edit button),
all rows are updating not just the row displayed. The second problem is I have an update_date and an Updated_by field with code in code behind in the Onitemupdating event and they are not updating at all. (This bit of code works fine in another page I have to updated similar fields on an insert).
I have a webpage which updates user information onto to the database, whenever they click the save buttonsince am using session variables in my page, data in the session variables is getting lost after 20mins if the session is idle, in order to keep the session alive am using the refresh option for every 5mins, after that the session variables are not lostNow my problem is whenever the page refreshes the user is losing all the data which is not saved, by means while the user is working on the page during the refresh all the textbox values are lostAny one has any solution for this? , can we extend the session variable timeout ?i tried this changed the session timeout to 60min in web.config as well, but still the session variable values are not persisting

I have two tables - one called Contract, one called Sow. Contract has a foreign key that points to SOW. What I'd like to do is to be able to edit the Contract details and provide a drop down list of different SOW records to choose from. The current code:
In my Contract Controller:
public ActionResult Edit(int id)
{
Contract contract = contractRepository.GetContract(id); [code]...
The list populates with values, but when I change them and update, the foreign key does not change.

I am using the following code to update the data in my datagrid.
But when I click update the value is updated in the database but it still shows old value in datagrid.
If I refresh the page after that then datagrid shows the updated value.

protected void MySQLDataGrid2_UpdateCommand(object source, DataGridCommandEventArgs e)
{
string newData;
TextBox aTextBox;
aTextBox = (TextBox)(e.Item.Cells[0].Controls[0]);
newData = aTextBox.Text;
decimal comm = Convert.ToDecimal(newData);
string UpdateHiveCommission = "Update tbl_HiveCommission set Commission = '" + Convert.ToDecimal(newData) + "'";
MySqlConnection objMyCon3 = new MySqlConnection(strProvider);
objMyCon3.Open();
MySqlCommand cmd3 = new MySqlCommand(UpdateHiveCommission, objMyCon3);
cmd3.ExecuteNonQuery();
objMyCon3.Close();
MySQLDataGrid2.EditItemIndex = -1;
MySQLDataGrid2.DataBind();

I'm just wondering if anyone has come across a good, easy method for updating a SQL Server 2000 DB table using the edit feature in GridView. The catch here is that I need it to encrypt, send to database, then decrypt when the page calls it to be displayed. I have successfully implemented an insert method using FormView with encryption. For some reason, I just can't seem to figure out the edit/update.
View 1 RepliesI have a DataList that on Update calls a function "DataList1_UpdateCommand" to update the data
OnUpdateCommand="DataList1_UpdateCommand"
It does not actually update the new value typed in. I placed a debug on the line below, but the text in the "FieldBalance" displays the original value and not the updated value, but the web pages does display what I typed in and not the original.
Dim FieldBalance As TextBox = CType(e.Item.FindControl("txtBalance"), TextBox)
Below is the DataList code and the DataList1_UpdateCommand sub

I have a page where I want to let the users vote on displayed items. My customer wants this done with an image and a VOTE FOR THIS link. The link and image are to disappear once the user has voted, and be replaced with the number of votes for that item. I've made the VOTE FOR THIS link a link button. I'm have two problems:
1) the ListView1_ItemCommand code is always excecuted twice, so the vote count is being incremented by two, not one each time someone votes.
2) A page refresh causes the ListView1_ItemCommand code to run (twice) so a page refresh also casts two votes for the item
If it makes a difference, I display one item per page.
I have a gridView that is populated with a dataset from an Oracle Database.
When I click on the EDIT button, it will redisplay my gridView with textboxes so I may make some changes.
Let's say one row is currently:
OPEN_TIME = 1 CLOSE_TIME = 2
When I click EDIT, 1 and 2 are in a textbox. If I change both values to 5 and click UPDATE, it will fire a RowUpdating..
Here is the code from my APP:
Private Sub gvBusinessHours_RowUpdating(sender As Object, e As System.Web.UI.WebControls.GridViewUpdateEventArgs) Handles gvBusinessHours.RowUpdating
Dim strOpenTime As String = DirectCast(gvBusinessHours.Rows(e.RowIndex).FindControl("txtOpenTime"), TextBox).Text
Dim strCloseTime As String = DirectCast(gvBusinessHours.Rows(e.RowIndex).FindControl("txtCloseTime"), TextBox).Text
End Sub
The problem is the values I am getting are the OLD ones and not the new ones... I am getting 1 and 2 and not 5 AND 5...
what I am doing wrong ?
I have an updatable Gridview control that I cannot seem to URL encode a textbox in one of the columns. I cannot encode some of the other controls in the row, so the solution from the msdn site doesn't work in my case. I only want to encode the single textbox. However, with the code I have, I don't get any errors, and the database is updated, but the column that is edited becomes empty in the database. Here is what I have in the gridview rowupdating:

I've the user creation form where a user will be created by entering username. Below that is checkboxlist for UserGroup which is binded with the dataset with the all the usergroup. Hence up on entering the username and checkbox selected(as the user can belong to multiple UserGroups).At database end, there are basically 3 tables-
Users(UserID,UserName)
UserToGroup(UserID,GroupID)
Groups(GroupID,GroupName)
So when i click create new user, the UserId along with GroupID(whichever checked) is saved into UserToGroup table.Im relative to this kind of process and hence facing setbacks. Can somebody help in end to end process. From front to DB SP.
here's the situation:
You're using NHibernate with Fluent NHibernate for mappings.
You have an application in production with a database with live data You're adding a new feature in development and it requires a new database column.
The new column cannot be blank. For example, I recently had to a DateCreated column to a table and the app now uses that date. As the only time the data will be missing is now, it seems unnecessary to add code to check for errors.
In my application I have an updater which can execute a SchemaUpdate to add the new database column - however, the application will starting crashing as it is expecting a value in the new column.
I need to get some sensible default data into that column. In this case I manually ran an Update to set the date to the current date (good enough for the situation). In this particular case I believe that you cannot set the column default to getdate() using fluent mappings.
Keep a schema version number in a config file In the updater that runs SchemaUpdate start adding upgrade methods for each version. These methods would run updates to add default data (or other required actions).
After the schema update has been run, call all methods required for a version greater than the current version (i.e. those that haven't previously been run). So if the app is now version 4 and version 2 is installed, methods 3 and 4 would be run.
